To all whom it may concern:

Be it known that I, ALBERT L. WOMAGK, citizen of the United States, residing at La Grange, in the county of Lewis and State of Missouri, have invented certain new and useful Improvements in Chart-Holders, of which the following is a specification.

This invention relates to devices for holding charts, maps, and thelike in convenient posit-ion for ready reference, which may be folded into small space when not required or for shipment-or storage.

Another object of the invention is to provide a simply constructed device which may be enlarged or reduced to correspond to the different sizes of charts or maps.

"With these and other objects in view the invention consists in certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claims; and in the drawings illustrative of the preferred embodiment of the invention Figure l is a perspective view of the improved device is operative position. Fig. 2 is a front elevation of one of the improved devices with the chart holder and charts removed. Fig. 3 parts shown in Fig. 2. Fig. 4 is a detached side elevation of one of the chart holders. Fig. 5 is an edge view of the parts shown in Fig. 4:. Fig. 6 is a perspective view of the casing in which the improved device may be stored or transported. Figs. 7 and 8 are detached views of the members employed for enlarging the device. Fig. 9 is aview similar to Fig. 2 illustrating a modification in the construction.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The improved device comprises a frame which is fo-ldable into small space when not in use, and which may be extended to correspond to the sizes of maps or charts, whereby the latter may be supported in convenient position for use, as for instance in a class room, and whereby any individual map or chart may be readily displayed and held in open position without removing the holder from the support.

The improved device comprises an upper portion formed of coacting members 1011 hingedly united at 1.2, and a lower portion formed of coacting members 13-14. hingedly united at 15. By this means the memis an end elevation'of the' bers l0l1 and 13-14E are respectively foldable back to back when not in use. The member 10 is provided with an outwardly directed flange 16, while the member 11 is provided with a similar outwardly directed flange 17, the confronting ends of the flanges being spaced apart a considerable distance, as illustrated in Figs. 1 and 2. The lower member 13 is provided with a. similar outwardly directed flange 18, while the member lei is provided with an outwardly directed flange 19, the confronting ends of the flanges 18l9 being spaced apart a distance corresponding to the spaced distance between the flanges 1617. The confronting ends of the flanges 1819 are provided respectively with pins 2021 which terminate at their inner ends in close proximity, as shown. Pivoted at 22 to one of the upper flanges, for instance the flange 16, is a hook member 23 adapted to engage over a pin 24 on the adjacent flange 17. By this means the space between the flanges 16-l7 may be covered, while at the same time the members 10l1 maybe locked in closed relations, the object to be hereafter explained.

Pivoted to each of the flanges is a stop device, and as the stop devices are precisely alike the description of one will sufl'ice for both. Each of the stop devices 25 is pivoted at 26 to one of the flanges and is adapted to be disposed in vertical position to prevent the displacement of the individual charts, as hereafter explained. The upper portion 10 may be formed integral with the lower portion, 13, as illustrated in Fig. 9, 01' formed in sections to enable it to be adjusted for charts of various sizes, as illustrated in Figs. 2 and 3. In the latter arrangement an interposed section formed of two parts 27-28 hingedly united at 29 and corresponding to the confronting ends of the upper and lower portions, and forming a continuation of the latter, as illustrated in Figs. 2 and 3. Means are provided for detachably uniting the upper and lower portions of the device with the interposed portions 2728, and for the purpose of illustration dowel pins 30 are shown arranged for this portion with set screws 31 for locking the dowel pins in position when the parts are united. By providing a plurality of the interposed sections 2728 of varying lengths the improved device may be readily adapted to maps or charts of various sizes. Any required number of the interposed sections of varying sizes may be employed, but for the purpose? of illustration three sizes of this portion of] the device are shown to illustrate tion of the device.

The chart holder portion of the device} the opera-;

'struction, can be inexpensively manufactured and of any required size and of any suitable material, and will be found very useful in schools and similar institutions, and will also be found useful for salesmen pins 20-2l' and between the confrontingp .{for holding certain kinds of goods in con- {venient position for ready reference or ex- ,hibition purposes.

Having thus described the invention, what is claimed as new is:

1. In a device of the class described, a

ends of the flanges 1819, while the oppo-lff support having lateral flanges at its tersite ends of the members 32-33 bear bef tween the confronting ends of the flanges, 16-17, as illustrated in Fig. l, and when;

thus arranged and the hook 23 closed, the,"

holder together with the charts will be maintained in position. When thus disposed all of the charts may be turned to the right or left and held in closed position by turn-. ing the members 25 in vertical position, or one or more of the charts may be disposed in'oppositedirections and held in that position by the members 25, as will be obvious. By this simple means any required chart may. be exposed for use, and the charts changed as required. Then not in use the v charts may be readily detached by releasing the hook 23 and folding the holder and de positing the same together with the chart in the casing, represented at 37. The latter may be provided with a suitable handle and will thus resemble the ordinary suitcase.

The improved device is simple in con- .minals with transverse recesses intern'iediate their ends, stop pins carried by one of said flanges and extending into one of said rccesses, a chart support having recesses in one end and engaging said pins, and means for holding said chart support at its other end in the other recess.

2. In a device of the class described a body having upper and lower lateral flanges, said flanges being formed in coacting sections spaced apart at their confronting ends, a holding device adapted to hold an object and bearing upon the body and engaging at its ends in the spaces between the flanges, and means for holding said supporting device relative to said flanges.

In testimony whereof I aflix my signature in presence of two witnesses.
